Traditionally, when carrying out circuit layout and design of circuit boards, the organization unit usually decides the appearance of the circuit board and the acceptable height and corresponding position of the parts installed on the board, and then the wiring of related components is handed over to the layout unit design.

However, because the circuit board graphics drawn by the organization will contain many different layers, and the information displayed on each layer is different, such as showing the location of specific parts on the circuit board or the height limit of the circuit board, etc. . Therefore, after drawing the image file, the user needs to spend a lot of time on arranging the image file and layers to obtain the required information or layer classification. In addition, if the output format used by each drawing department is different, additional format confirmation is required. Furthermore, organization units often make organization corrections according to the use environment. Once a certain correction point is ignored and the layout unit is not reminded to make corresponding corrections, subsequent wiring errors will be caused, which will bring great harm to the personnel of the two departments. Great inconvenience and hassle. In addition, traditionally, the comparison before and after correction is performed by the painter himself.

detailed description

In order to make the description of the present invention more detailed and complete, reference may be made to the drawings and various embodiments described below, and the same numbers in the drawings represent the same or similar elements. However, the provided embodiments are not intended to limit the scope of the present invention, and the description of the structure and operation is not intended to limit the order of its execution. Any structure recombined by components to produce a device with equivalent functions is included in the present invention. scope covered by the invention.

The accompanying drawings are for illustration purposes only and are not drawn to original scale. On the other hand, well-known elements and steps have not been described in the embodiments in order to avoid unnecessarily limiting the invention.

FIG. 1 is a flowchart of a method for generating graphics according to a preferred embodiment of the present invention. The graphics generation method 100 is used for real-time classification and version comparison of a generated graphics to reduce the occurrence of human errors. Wherein, the method for real-time classification and version comparison can be implemented as a computer program and stored in a computer-readable recording medium, so that a computer or an electronic device can read the recording medium and execute the A method for playing multimedia on a virtual desktop. The computer-readable recording medium can be a read-only memory, flash memory, floppy disk, hard disk, optical disk, U-disk, magnetic tape, a database that can be accessed by the network, or a computer-readable recording medium with the same function can be easily imagined by those familiar with the technology .

In this graphic generation method 100, firstly start a graphic generation auxiliary system in step 101, then set a drawing mode in step 110, so as to select a three-dimensional figure or draw according to the drawing mode to generate a three-dimensional figure, and according to the drawing mode, as a classification for this 3D shape. Traditionally, after drawing circuit board graphics, mechanical engineers need to sort out the relevant information needed to classify the drawings and layers by themselves, so as to provide subsequent layout units for wiring design of related components, which is inconvenient. Therefore, when the present invention draws graphics, the user can set a drawing mode on a graphics generation system earlier, allowing the user to select a three-dimensional figure or draw a sketch in this drawing mode, and when the drawing is completed, the sketch will be drawn. The drawing mode is directly classified according to this. In one embodiment, the drawing mode may include drawing the height-limited area, drawing the exposed copper area, and drawing the white paint area, but is not limited to the above-mentioned drawing modes. Accordingly, when the drawing mode selected by a user is to draw the height-limited area, the user can select a 3D circuit board graphic provided by the system according to the height-limited area to be drawn, and draw the 3D circuit board graphic The height limit area is marked on it, and a three-dimensional circuit board graphic with a height limit area is generated. Then the system will automatically classify the 3D circuit board graphics according to this drawing mode, that is, classify it under the drawing category of height-limited area. Therefore, as far as the user is concerned, after the drawing is completed, there is no need to reorganize the related information required for the classification of the map files and layers. In addition to reducing the workload, it can also avoid classification differences caused by personal classification habits. In another embodiment, if the finite height area has been drawn on the 3D circuit board graphic but not classified, the system can also classify the 3D graphic according to the drawing mode set by the user. For example, if you choose to draw the height limit area, the system will automatically classify this 3D circuit board graphic under the category of height limit area drawing.

Next, in step 120, the classified 3D graphics are converted according to the corresponding drawing mode to generate a 2D preview image file, and each 2D preview image file includes at least one 2D graphic. In order to avoid errors in the exported image file, the system can provide a preview function before the user exports the image file, allowing the user to confirm whether each graphic in the image file is wrong. Among them, the preview image files provided are classified two-dimensional image files, that is to say, although the user is drawing three-dimensional graphics, the system will convert the classified three-dimensional graphics into a two-dimensional preview image file for user confirmation. Therefore, under this system, the user only needs to draw a 3D graphic, and the completed 3D graphic will be automatically converted into a 2D graphic file, and a corresponding 2D preview graphic will be generated according to the drawing type for the user to confirm. Therefore, the user does not need to perform file conversion and select the previewed 2D graphic from the 2D graphic file, the system will automatically complete the conversion and provide a preview. The two-dimensional preview image file generated therein, under this embodiment, may contain a plurality of two-dimensional graphics belonging to three categories, which are respectively two-dimensional graphics for displaying height-limited areas and two-dimensional graphics for displaying exposed copper areas. Two-dimensional graphics and two-dimensional graphics showing areas of white paint, but not limited to the graphics described above.

In another embodiment, this application can also automatically distinguish the height-limited area, exposed copper area, or white paint area displayed in the two-dimensional graph into the on-board information of the circuit board or the information under the circuit board. That is to say, before the two-dimensional preview image file is generated in step 120, the present invention will define a virtual information dividing line at about half the thickness of the circuit board according to the cross-sectional view of the circuit board, and place the circuit board on the information dividing line Information is defined as on-board information, that is, information on the front of the circuit board. The circuit board information located below the information dividing line is defined as under-board information, that is, the information on the back of the circuit board. And according to the information dividing line, the generated two-dimensional preview graphics are further distinguished to respectively display the on-board information and off-board information under each category. In other words, the two-dimensional graphics included in the two-dimensional image file to display the height limit area, exposed copper area and white paint area can be expanded to display the upper limit height area of the board, the lower limit height area of the board, and the exposed area on the board. 2D graph of copper area, exposed copper area under board, white paint area on board, and white paint area under board. Therefore, step 110 may also include the region information segmentation process shown in Figure 2. In step 111, a virtual information dividing line is defined in the three-dimensional graphics, wherein the graphics on the dividing line are defined as board graphics, located here The graphics below the dividing line are defined as graphics under the board. And step 112, convert the classified three-dimensional graphics according to the virtual information dividing line to generate a two-dimensional preview image file, each two-dimensional preview image file includes a plurality of two-dimensional graphics, respectively displaying boards under each category Information above and below the board.

Then in step 130, export each 2D graphics in the preview image file according to a 2D image file format. That is, after the user confirms that there is no error in the 2D graphics in the preview file, each 2D graphic in the preview file can be exported sequentially according to a 2D file format for archiving and subsequent Comparison. In other words, besides being stored on the user end, such as a computer, the exported 2D graphics will also be sent to a remote server for version comparison. In one embodiment, the 2D graphic file format is a DXF file format, where DXF is the abbreviation of DrawingInterchangeFormat or DrawingExchangeFormat. According to the classification generated by the drawing mode of this case, it includes height limit area, exposed copper area and white paint area. Therefore, the exported two-dimensional graphics include board upper limit height zoning map, board lower limit height zoning map, board exposed copper area map, under board Partition diagram of exposed copper, partition diagram of white paint on the board, partition diagram of white paint under the board, board frame diagram, part data sheet and part location diagram, but not limited to this.

Then in step 140, the two-dimensional graphics are compared with a historical graphic file to generate a comparison result analysis table. Before the product is completed, it is often revised several times according to the use environment, and the mechanism design of the circuit board is also the same. In order to avoid troubles for subsequent units due to uninformed corrections. Therefore, the system transmits these two-dimensional graphics to a comparison device for comparison with the historical graphic files in the comparison device, and marks the difference points to generate a comparison result analysis table to be fed back to the user terminal. In one embodiment, the comparison device can be a remote comparison device, such as a server coupled to multiple client terminals, which can handle the comparison requirements of these client terminals. The 2D graphics transmitted to the comparing device will be stored as a historical graphic file for comparison with the 2D graphics transmitted next time. That is to say, the two-dimensional graphics transmitted this time will be compared with the two-dimensional graphics transmitted last time to confirm and mark the differences between the two, for example, the differences can be marked with different colors. In another embodiment, the user can also choose the version to be compared with the 2D graphics transmitted this time, and is not limited to only comparing with the 2D graphics transmitted last time.

In addition, when comparing traditionally, a specific position in the two-dimensional graphics of the circuit board, such as a hole, is used as a reference point for comparison. Points are overlaid and compared to avoid shifting the comparison position. However, the circuit board may have undergone multiple corrections, causing specific positions to shift or disappear, affecting subsequent comparison results. Therefore, in order to ensure that each comparison is performed using the same fixed reference point, the present invention will generate a special symbol (such as a circle, triangle, etc.) outside the circuit graphics in the two-dimensional graphics before the two-dimensional graphics are exported. and other shapes) as a reference point for comparison. In order to avoid misidentification, this special symbol can have a special size (this special size can be extremely small, and the user may not be able to see it with the naked eye, so as to avoid misleading the user to draw a drawing) , therefore, the comparison device can search for the comparison reference point for comparison by screening the special size. Since the comparison reference point is additionally set and located outside the circuit pattern, even if the circuit board is corrected, it will not affect the comparison reference point, so the subsequent comparison results can be improved. Therefore, step 140 of the present invention also includes a comparison process as shown in FIG. Outside the circuit board graphics, for example, for a notebook computer, the reference point for this virtual comparison is the position of the middle point of the two ends of the hinge. And in step 142, superimpose the two-dimensional graphics to be compared with a historical graphic file according to the virtual comparison reference point, to confirm and mark the differences between the two, so as to generate a comparison result analysis table.

Finally in step 150, the comparison result analysis table is sent to the user. After the comparison is completed, the comparison device will return the comparison result analysis table to the user, and the user decides whether to activate the graphic generation auxiliary system for drawing again (step 101). By comparing the result analysis table, the user can know the difference between the previous version and the previous version, that is, the correction point. In addition to reminding the user whether he has completed all corrections to be corrected, it can also remind the follow-up unit to make corresponding corrections. Because this comparison is performed by the comparison device, in addition to avoiding human error, it can also increase the comparison accuracy.
